Plotly.js: Plotly 1.42.1 goes unresponsive

[rfriedma]

I recently updated from plotly 1.41 to 1.42.1 in order to get some bug fixes. With the same data, plotting is now going unresponsive. I have two links below showing the same data in two versions of plotly where one hangs.
I'm using Chrome 70.0.3538.67 (Official Build) (64-bit)

Here's 1.42.1:

Here's 1.41.0:

Can anyone determine something wrong with my data or explain why plotly is hanging?

Thanks

Thanks very much for writing in.

Unfortunately, nothing comes to mind at first glance. We'll investigate.

there's a runaway while loop here:

Came in with #3087
@archmoj want to take this?
